<h4><a name = "tag_002_001_645">&nbsp;</a>NAME</h4><blockquote>
syncok, wcursyncup, wsyncdown, wsyncup - synchronise a window with its
parents or children
</blockquote><h4><a name = "tag_002_001_646">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="curses.h.html">curses.h</a>&gt;

int syncok(WINDOW *<i>win</i>, bool <i>bf</i>);

void wcursyncup(WINDOW *<i>win</i>);

void wsyncdown(WINDOW *<i>win</i>);

void wsyncup(WINDOW *<i>win</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_002_001_647">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>syncok()</i>
function determines whether all ancestors of the specified window
are implicitly touched whenever there is a change in the window.
If <i>bf</i> is TRUE, such implicit touching occurs.
If <i>bf</i> is FALSE, such implicit touching does not occur.
The initial state is FALSE.
<p>
The
<i>wcursyncup()</i>
function updates the current cursor position of the ancestors of <i>win</i>
to reflect the current cursor position of <i>win</i>.
<p>
The
<i>wsyncdown()</i>
function touches <i>win</i> if any ancestor window has been touched.
<p>
The
<i>wsyncup()</i>
function unconditionally touches all ancestors of <i>win</i>.
</blockquote><h4><a name = "tag_002_001_648">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion,
<i>syncok()</i>
returns OK.  Otherwise, it returns ERR.
<p>
The other functions do not return a value.
</blockquote><h4><a name = "tag_002_001_649">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_002_001_650">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
Applications seldom call
<i>wsyncdown()</i>
because it is called by all refresh operations.
